 QALY = quality adjusted life year. Costs are in 2011/12 UK£. Figures are expected values per patient with 95% confidence intervals in brackets. The point estimates are calculated using base case values of the model parameters (deterministic results). The 95% confidence intervals are derived using standard deviations calculated from the 5000 simulations in the probabilistic sensitivity analysis. The monetary net benefit is calculated at a maximum willingness to pay for a QALY of £20 000 and £30 000. The results are calculated using base case values of the model parameters. Numbers may not sum due to rounding.
